| // Now that you have used .forEach(), .map(), .filter(), and .reduce(). I want you to think of potential problems you could solve given the data set and the 5k fun run theme. Try to create and then solve 3 unique problems using one or many of the array methods listed above. |

this one has a different pattern from the others. Read carefully what it's asking, and compare to the solution code
function contains(item, list, cb) {
// contains checks if an item is present inside of the given array/list.
// Pass true to the callback if it is, otherwise pass false.
for (let i = 0; i < list.length; i++) {
if (list[i] === item) {
return cb(true);
}
}
return cb(false);
}

| // Pass the duplicate free array to the callback function. | ||
| // Do not mutate the original array. | ||
| const noDoubles = array.filter((item, index) => array.indexOf(item) >= index); |
| }; | ||
| return counter; | ||

excellent, looks like you're locked in on closures if you get this one
